I am interested in cognitive modeling. Based on the ACT-R theory of human cognition, I have developed a computational model that provides insight into how much practice is needed by a human to progress from novice to expert level in learning a user interface layout. I have also developed a closed-form model that provides insight into how mentally effortful is it to learn a user interface layout relative to other user interface layouts. This closed-form model is an analytical approximation that is based on the declarative memory equations of ACT-R.

I obtained my PhD in Computer Science at York University, Toronto, Canada in October 2014. My doctoral research involved creation of cognitive models in the domain of human learning. My doctoral dissertation supervisor was Wolfgang Stuerzlinger. My external examiner was Frank E. Ritter. The title of my thesis was ACT-R Based Models For Learning Interactive Layouts. My PhD dissertation can be found here.

Miscellaneous
My PhD Convocation Webcast: My PhD convocation was held in Ceremony #1 on Wednesday, October 15, 2014. I can be seen receiving my certificate in a webcast by York University, Toronto, Canada. I receive my certificate from the Chancellor of the University approximately between 47th and 48th minute of the webcast. To see the webcast, you may click here.
